## Questions & Answers

**Q: Why does water remain at the bottom of the drain core?**
A: The drain keeps a bit of water at the bottom to stop bad smells and water from flowing back. This water barrier is like a mini-pond that gets refreshed every time you use the drain.

**Q: How should I choose between the 2.4‘’ and 3.3‘’ depth specifications?**
A: The deeper the specification, the more water it holds. If you're going to be away on a trip or business for an extended period without draining, the deeper specification will maintain the odor control for a longer time.(2.4''-20days ; 3.3''- 40days )

### ⭐⭐⭐⭐⭐ Fits great, Easy install and does the job
*by D***R on 28 February 2025*

I had a standing shower that did not have a p trap under the drain. Bathroom smelled because of sewage gas travelling back into the bathroom. This did the trick as it holds enough water to block any smell that P trap is supposed to do. Great buy and I would recommend it.
